It's not my opinion that matters here it's yours. You are obviouly unhappy with the marks and are asking what can you do to get rid of them.

my view is that if it's a new boat then it's the dealers problem and not yours. the easiest way to make them pay attention is to start mumling about a lack of merchantable quality and see if they take an interest
